Cannot tab through fields

[Saurabh D]

Hi,

I'm using the PDF Viewer to display documents to the user in a browser so they can fill in the form fields. When filling the form, the tab key should highlight the next field in the form, but in case of PDF Viewer, it is highlighting any other field randomly, sometimes on a different page. Because of this, the user cannot tab from one field to the next and instead has to select the field using the mouse before entering the text. Can you please advise if this is a bug or if there is any workaround.

Thanks.

Hi Saurabh

Hi Akshaya,

Sure, please refer to the attached project. Steps to reproduce the problem:

1. Run the attached project - this should load the PDF document in the PDF Viewer
2. Highlight line 2.a. Family Name
3. Hit Tab key - this will highlight line 2.b.
4. Hit Tab key again - this will highlight line 2.c - so far so good
5. Hit Tab key again - this will highlight line 4.c, which is out of sequence (it should have highlighted line 3.a.)
6. Continue to hit Tab key and you will see the highlighting jump all over the place.

Ideally, when a user is filling the form, they would want to hit tab key to navigate to the next field and continue typing into that field.

Thanks for looking into this.

Hi Saurabh, 

Thank you for your patience.  

We will navigate to the fields based on the PDF document structure not on the order in which the fields are in the document. For the provided PDF document, the fields position is 2a,2b,2c,3a but in the PDF document structure the fields are arranged in 2a,2b,2c,4c. So, we will navigate as in the document structure. 

Note: We have checked the same with google chrome and other competitors’, they also navigated as same as of PDF Viewer control.

Hi Akshaya,

Sorry to follow up late, but this is actually becoming an issue for us - for e.g., if you open the document in Adobe PDF reader, the tabbing works perfectly fine. When a user is filling a form that has potentially hundreds of fields, it is very tedious to keep clicking on each field before typing.

Could you please take a second look at this and let me know if this can be addressed in a future release?

Thanks.

Hello - I am experiencing this issue in the EJ2 ASP NET MVC PDFViewer. The tab order is going all over the place. I attached a video showing the issue, as well as the PDF we are using. The first PDF up is in Syncfusion, then I switch to Microsoft Edges PDF viewer to show the tab order is working as intended. I am using version 27.1.50.
